About the MB Quart JC1-108

Take to the (off) road with better sound
Take to the (off) road with better sound
It's fun tricking out your Jeep for tooling around town or going overland. But before you start bolting gear onto the outside, why not improve the audio inside? MB Quart makes it well worth your time with their JC1-108 3-1/2" coaxial speakers. Specifically designed to fit in the upper dash of your Jeep, you can bolt these speakers right in place of the factory speakers. But that's where the similarity ends — the paper/mica woofers and magnesium tweeters of these speakers kick out sound that'll make you realize exactly what you were missing before.
Plug 'em in
The speakers come with factory-compatible plugs — no splicing required. MB Quart provides vehicle-specific instructions to eliminate the guesswork, too.
